[All

rial, is secured to the back portion of each brush and extends outwardlywell toward the ends of the tufts or bristles'of the brush vtion forcarpet sweepers are supported on pivots 24 in the ends of the case, andare adapted to close up against the sides 7, as clearly appears in Fig.II. These are controlled by links 28-28, which are connected by ivots 31to the hand-lever 29,.which-is fulcrumed at 30in the end of the case, sothat the dust-pan can be readily dumped. The outer edges of thedust-panfitinto recesses 25 in the sides 7 of the case.

A flexible apron 26 is provided on each dust-pan 23, to which is secureda rigid bar 27, formed preferably of a fold of sheet metal. This bardrags along the floor and the apron affords a very effective inclinesurface for the dust and dirt that is swept by the brush thus readilycollected and passed up into the pans. As this apron is flexible and isweighted, it rests very close to the floor and the operation of thedevice is exceedingly effective. The collector at the rear folds backunder the pan, making a tight joint and compelling the air to circulateout through and above the pans. Wire screens 33, with fabric linings 33are covered-over windows or openings in the sides 7 of the case abovethe dust pans and permit the air to readily circulate therethrough andcollect the dust which drops down into the dust pans 23. f

A-handle 34, with a suitable bail connection 35, withvpivot pins 36, 'isprovided for manipulation of the sweeper. This bail is held in centralposition by the balancing springs 37-37, which are connected fromopposite sides of the case. See Fig. I.

I have shown my improved structure in its referred form. The spiral flatbrushes, wit flexible backings, secure a very effece tive sweepingaction, which eoaets effectively with the dust collectors 26, but thesedust collectors would also be effective with other styles of brushes. Iknow from observation and test that the weight bars 27 might be omittedand the device would 0 erate quite eflectively, though the weig t barsare of decided advantage. The parthat the sweeper so that the dirt anddust is ticular construction I have adopted enables the application ofthe spring pressure very effectively, as I have indicated, and thismeans would likely be valuable in other kinds and styles of sweepers.

The dust pans and their dumping means can be of any desired form, theform I have shown being slightly modified from the standard constructionof carpet sweepers. It is of advantage that the brush sections beadjustable on the radial arms, but it is clear would be effective for along time if this adjustable feature was not incorporated in thesweeper.

In Figs. V and VI, I show a in which the brush members, in place ofbeing spiral, are straight, like the blades of a fan in a fanning mill.This makes an effective structure, butit' is not nearly so effective asthe spiral-arrangement, and is slightly irregular in its operation.

I desire to claim the. invention in the specific form in which I haveillustrated it because I believe the parts coact, but I also desire toclaim the combination broadly, and also to claim the various novelsub-combinations which are present in the structure.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. In a carpet sweeper the combination with a suitable case with acentral openinlg1 .in. the end and screened apertures at eac side; askeleton fan 'brush, the blades of which are of spiral'form,

with its axis lengthwise of said case; drivin traction wheels suitablyconnected to 'drive the said brush; and dust pans supported in the lowerpart of said case beneath the screened openings in the sides of the caseto receive the dust collected by said fan brush.

2. In a carpet sweeper, the combination with a suitable case with acentral opening in the end and screened apertures at each side; askeleton fan brush centrally disposed with its axis lengthwise of saidcase; dnving traction wheels suitably connected to drive the said brush;and dust pans supported in the lower part. of said case beneath thescreened openings in the sides of the case to receive the dust collectedby said fan brush.

3. In a carpet sweeper, the combination of a suitable case; a rotatablebrush therein; traction driving wheels for actuating the said brush; apivoted dustl pan su ported in the lower part-of said case and disposedto receive the dust collected by said brush; flexible dust apronssecured to said dust pans on the sides toward the brush and disposed tocontact with the floor beneath and to coact with said brush, asspecified.

4. In a carpet sweeper, the combination of centrally disposed a suitablecase; a rotatable brush therein; traction and drivin wheels foractuating the'said brush; suita 1e axles on'which said driving Wheelsrevolve, disposed in suitable 5 slots at the ends of the case; springpressure bolts connected to the centers of said axles and supported onthe sides of the case for putting tension thereon; oblique springsconnected to said axles toward each end and 10 disposed to draw the sameinwardly; and

suitable dust as specified.

In witness whereof,

pans for collecting the dust,

I have hereunto set my hand and seal in the presence oftwo Witnesses.
